An analog baseband chain for a multistandard (Bluetooth, WCDMA/UMTS, and WLAN) reconfigurable receiver in a 0.13 µm CMOS occupying 1.65 mm2 is presented. The circuit consists of an open-loop programmable-gain amplifier (PGA1), an Active-Gm-RC low-pass filter (LPF), and a closed-loop programmable-gain amplifier (PGA2). The chain gain can be programmed in the range -6dB-to-68 dB, while the input-referred noise (IRN) is 5 nV/sqry(Hz). A dynamic range (DR) larger than 82dB is achieved for a 1% total harmonic distortion (THD). The current consumption is minimized and adjusted for the different operation conditions, down to 11 mA for the full chain.
